Discover — WU -17.17% + 2 more (5:00 PM ET)

$WU collapsed 17.17% in after-hours Friday, hitting $6.36 on $55.5M in dollar-volume.

Western Union dropped from a $7.69 prior close to $6.36, with $55.5M in after-hours dollar-volume confirming this is not a low-liquidity ghost move. That volume weight behind a sub-$7 print is the flag — watch for whether $6.36 holds as a level or acts as a breakdown pivot into Sunday night futures open.

Other names crossing threshold this cycle:

• ▸BHC +16.09% to $6.89 (prev $6.03) — mirror-image surge on $22.3M dollar-volume, notable given the sub-$10 price range where moves of this magnitude can accelerate quickly.
• ▸AMZN +15.09% to $271.58 (prev $235.50) — $128.5M in after-hours dollar-volume makes this the heaviest liquidity event of the cycle; a $36 handle move at this price demands attention heading into the Sunday open.
